Introduction:

Hand-to-hand bioelectrical impedance analysis (HH BIA) is a widely used, cost-effective method for estimating body fat percentage (%BF). While it is a reliable technique, questions regarding its validity remain, especially concerning how elbow position influences measurement outcomes. This study examines whether elbow angle affects the accuracy and consistency of HH BIA in measuring %BF.

Key Findings

  • The study assessed HH BIA measurements in 44 males and 24 females at two elbow positions: flexed at 90° (IN) and fully extended (OUT).
  • The IN position yielded %BF values approximately 4% lower than the OUT position.
  • Reliability for both positions was high (ICC=0.99), but the OUT position overestimated %BF compared to air displacement plethysmography (BOD POD®).
  • The IN position provided a closer match to the BOD POD® measurements, making it a potentially more valid option for HH BIA.

Integration of External Medical Sources:

According to the American College of Sports Medicine (ACSM), accurate body composition measurement is crucial for assessing health risks related to obesity and performance optimization in athletes. Ensuring the validity of HH BIA is essential for these applications.
